System for calculating whether time-crucial shipment is located according to expectation

ABSTRACT

A client-server system and method for calculating whether time-crucial shipment is located according to expectation comprising a device and a remote special purpose computer, the device comprising a non-lithium battery; a Wi-Fi receiver; a GSM module; an accelerometer; a Wi-Fi antenna; a GSM antenna; and a microcontroller programmed to store identification data of each Wi-Fi access point within range and time each Wi-Fi access point was accessed, to automatically turn off the GSM module when aircraft engine vibration is detected; and to automatically transmit via GSM protocol the Wi-Fi access point data when aircraft engine vibration is no longer detected. 
     The remote special purpose computer uses a flight plans database and a Wi-Fi access point database to calculate location of the device based on the Wi-Fi access point data received via GSM and compare the calculated location to an expected location based on a flight plan.

BACKGROUND OF THE INVENTION

This invention relates to the field of logistics. More particularly the invention relates to systems and methods of tracking location of a package which is en route from a shipping location to a destination location, and to systems and methods to ensure that an extremely time-critical delivery is proceeding according to schedule and to alert the shipper or recipient or a designated third party if there is a problem with shipment such as a flight delay or mishandled package or misdirected delivery.

Sometimes next day shipping service just isn't fast enough when a customer needs a replacement part for an assembly line that's down, or a part is needed for an aircraft that is idle because of part missing, or a human organ needs to be shipped for transplant across the continent, or tissue samples, bone marrow or eye for transplant needs next flight out speed. In such cases the shipper or recipient will engage a private logistics shipment service, commercial airline carrier, charter flight, or Next Flight Out (NFO) delivery service to transport the package since time is so critical. In other cases the parties may elect to use one or more common carriers to transport the package from pick up to delivery such as planes, trains, and/or trucks that operate according to a schedule.

Some existing services such as Amazon, Wal-Mart, Federal Express, DHL, scheduled air carriers, and the like offer same day delivery to certain locations. However, even though such services are generally reliable and offer tracking services, occasionally mistakes happen during shipments, for example a package may miss a flight or a truck may be delayed due to weather, accident, or traffic conditions and so even if the chances of such a mistake are very small, for extremely time-sensitive shipments such as the above-mentioned situations there is a need for extremely accurate tracking systems and methods which are superior to state of the art methods.

SUMMARY OF THE INVENTION

This need, and others which will become apparent from the following disclosure and drawings, is addressed by the present invention which comprises in one aspect a system comprising a client device which is adapted for being adhered to or placed within a time-crucial package, the device configured to receive a Wi-Fi signal from a Wi-Fi access point and to communicate data to one or more servers via GSM wireless transmission protocol; and one or more servers configured to receive data via GSM from the device and to receive schedule data from a flight tracking service, the one or more servers programmed to determine location of the device at a given time by comparing the data received from the device to a database of Wi-Fi access point locations, the one or more servers programmed to compare the determined location to a scheduled location according to the data received from the flight tracking service.

In another aspect the invention comprises a method of determining the location of a package at a given time comprising comparing data received via GSM protocol from a device which obtained the identification data from a set of Wi-Fi access points to a known location of each Wi-Fi access point to a scheduled location obtained from a flight tracking service, thereby calculating whether the device is located according to the scheduled location. In another aspect the method comprises signaling an alarm if the device is not located according to the scheduled location and reporting the last known location according to data received via GSM protocol from the device. Another aspect of the method includes a step of reporting received signal strength from one or more known Wi-Fi access points and time of reception of the signal. In some embodiments a GSM communication gateway allows for both USSD or SMS, two types of messages, to be sent.

The system can make battery saving decisions based on a variety of factors in the supply chain. For instance, a system that has additional information on location availability or route delays based on flight database schedules can dynamically adjust the location update frequency of the device to save power. Additionally, the system can increase frequency or change modes to ensure supply chain compliance or gain additional information about the location state of the shipment and its environment.

With emergence of the Next Flight Out (NFO) air transportation market for critical shipments, when time and mission critical logistic requirements needs shipments delivered within hours, not days, planning the best flight path and being able to adopt and react to exception reporting with confirmations of the location of each shipment at any point and time worldwide is critical to ensure on-time delivery.

Once the package has been tendered to an airline, the airline is not obligated to provide any updates as to whether the package made it on the desired flight. A common practice is barcode scanning each piece as it is loaded onto the airplane. That allows the shipper to login to a custom airline cargo portal to see if it has made the flight.

There are two main problems with both of these current systems. The first and most problematic are the false positives. It is very common for an airline to scan a piece indicating that it was loaded onto the plane and then have that piece be intentionally refused, left on the loading dock or unloaded. This means that when the shipper logs in, they see that the shipment was verified onboard and they can expect to recover it one hour after the plane lands when it is released from cargo. In the case of a five-hour cross-country flight, there is no indication of error or delay for six hours. Once it is established that the piece is not at the destination airport, a game of finger pointing ensues. The destination airport calls the departure airport saying the package never arrived. The departure airport insists that it is at the destination airport because it was scanned on board the plane. The destination airport searches again and the calls the departure airport insisting that it never arrived. Finally, the departure airport searches the dock and finds the piece. At this point, hours have passed and the shipment has still not left the origin city and needs to be placed on a new flight.

The package being left at the departure airport without notice is a much too common case. A less common, but even more costly case is when a shipment is loaded on the wrong aircraft. The shelving and organization system airlines use is very manual with little verification. A package meant for Kansas may end up on a flight to Korea simply because they are proximal to each other in the cargo area. A mistake of this nature can delay the shipment by days. In the case of a critical shipment like a human organ or part for a downed aircraft or machine, the associated costs can be significant.

The second problem with relying on airline notifications of on-boarding is that they are separate closed systems with very little control and transparency for the people that are relying on those systems to be correct. Each of them functions differently with a varying degree of success. A system that is designed to track critical organ deliveries cannot interface with every airline or common carrier over email.

A definitive measure of both takeoff and landing is required in order to have a closed supply chain that critical shipments can use to mitigate delays in real-time. Those messages need to interface with complex shipment tracking systems to notify operators as soon as an error occurs in order to minimize supply chain down time.

The location monitoring apparatus attached or inside package finds Wi-Fi networks in-range and sends the router's BSSID/MAC address, report time, and signal strength, over wireless communication methods, The reported device data is communicated to computer servers and by API and computer database with router-specific MAC addresses to be matched though third party mapping and location engines or other Wi-Fi Point of Interest databases (i.e., specific Wi-Fi BSSID/MAC address of aircraft or near runways) with collected Wi-Fi location coordinate matching records to determine a package or other shipment's location(s) en route. Accurate location capabilities, combined with real-time Wi-Fi network location intelligence data offer increased efficiency in resource and supply chain management, with lower cost and significant less device power consumption than conventional higher power GPS tracking solutions. Accuracy is also significantly improved since one or more Wi-Fi data sources can be specific to a floor, room, warehouse or even a specific aircraft's wireless access point(s) where traditional. GPS systems are limited to only reporting latitude and longitude coordinates.

The system and method provide real-time location with Wi-Fi signal intelligence to determine the package's location en route.

The present invention improves en route package exception reporting and delivery processing for time-critical shipments with a system accessible to the global supply chain with a low cost data reporting device adding real-time, accurate location granularity for both indoor and outdoor location determinations, combined into a market-ready internet-of things (IoT) system with integration into logistic carriers and enterprise management API's, flight databases and computer servers to exchange and process en route location reporting data between the electronic device on or within package, and third party computer server(s) processing the data received over wireless GSM transmission networks. This is crucial and beneficial for package shipments en route or when package is in enclosed within en route or pre-flight indoor environments (i.e., an aircraft hanger), and improves upon prior art that rely on GPS location where GPS signals are blocked. Examples of blocked GPS signals include in-aircraft cargo holding areas and logistics service holding warehouses and indoor package transfer areas that lack access to GPS satellites, representing one of several improvements over prior art.

DETAILED DESCRIPTION OF THE INVENTION

According to a first embodiment of the invention, referring to FIG. 1, the device 11 includes a Wi-Fi receiver 17, a microcontroller unit (“MCU”) 20, a Bluetooth module 3, a GSM module 6, an accelerometer 5, a Wi-Fi antenna 14, a GSM antenna 8, a lithium-free battery 16 which is disconnected from the remainder of the device 11 by pull tab 2. The MCU 20 sends instructions to and receives data from an accelerometer 5, GSM module 6, Bluetooth module 3, and Wi-Fi receiver 17. The device also includes an embedded SIM card 18. The device 11 includes a WiFi antenna 14 which receives signals broadcast by nearby Wi-Fi access points 47 for the Wi-Fi receiver 17, and a GSM antenna 8 which communicates with GSM cell towers 13 within range of the device 11. GSM signals from a GSM network 12 are also received by GSM antenna 8 and sent to GSM module 6. Device 11 includes a lithium free primary battery 16 so that device 11 is compliant with US FAA regulations and for safety reasons in all countries. The device 11 also includes an embedded SIM card 18 which identifies the device for the GSM network 12. The device 11 can communicate via Bluetooth protocol using its Bluetooth module 3 and Bluetooth antenna 15, for example to a mobile device 1 which receives data from server 4. The device 11 does not store Wi-Fi information but rather only detects Wi-Fi signals when it needs to transmit a location. Every location transmitted by the device is it's actual location, not a previous one.

An embodiment of the special purpose computer server 4 is shown in schematic form in FIG. 2 wherein the server 4 includes in memory an access point and cell tower database 9, a flight plans database 10, and a processor which is programmed to carry out the functions of the server 4. The special purpose computer communicates with a USSD gateway 11 which communicates with the device 11 over SS7 signaling over GSM network 12.

In overall operation, the device 11 is placed in or on a package prior to shipment of the package via truck, train, and/or scheduled aircraft. Along the way the device 11 encounters Wi-Fi access points of varying signal strength and sends the MAC address and SSID of the encountered Wi-Fi access points of the respective encounters to one or more servers 4 which function as a special purpose computer. The servers 4 use a calculated flight and/or transit plan based on pickup time and location, flight, truck, and train schedules received from third party sources, and destination location and required minimum delivery time to plan a schedule route. The device 11 is programmed to turn on when power is turned on, for example when the battery 16 is connected by pulling out a power activation pull tab 2. The device 11 is also programmed to process accelerometer 5 data and calculate when the device 11 is vibrating in a pattern which implies the device 11 is aboard an aircraft with engines running, in which case the device 11 can automatically turn off its GSM module 6 to prevent transmission of data while the aircraft is flying and turns on its GSM module 6 when the absence of such a vibration pattern implies the device 11 is no longer on an aircraft whose engines are running.

When the GSM module 6 is on, the device 11 periodically broadcasts via GSM antenna 8 the Wi-Fi access point 47 data in range of device 11 which is received at GSM cell towers 13 and which is received in turn by the servers 4 via GSM network 12. The servers 4 compare expected locations to one or more Wi-Fi access point 47 encounters received from the device to determine if the device is located where it is expected. If the device location does not match an expected location at an expected encounter time a notification is issued, for example an alarm notification or an automated phone call to a designated phone number, an alert to third party sever, an e-mail, an SMS message, or other user machine interface.

The client device communicates data by a GSM communication gateway from its GSM transmission module 6 that allows both USSD or SMS short data messaging, to be sent to a remote special purpose computer 4. USSD is the preferred method since it is a short message data format (i.e., typically 160 bytes or 182 alphanumeric characters) that has the advantage of using less transmission power thus preserving device battery power to last across international transport schedules or during extended shipping route delay.

FIG. 1 illustrates a system including a courier driver mobile communication device such as a cell phone 1 or other mobile computing device which receives instruction from a special purpose computer 4 which functions as one or more servers, referred to herein as “AirTrace™,” on an app running on the driver cell phone 1 for a new package to be picked up at a specific location. The driver is instructed to attach or install a device 11, referred to herein as “AirTrace tracker,” in the package or onto package by self-adhesive attachment means when it is picked up.

In this first embodiment the device 11 comprises a non-lithium battery 16, memory 6, an accelerometer 5, a GSM module 6, a Wi-Fi receiver 17, a microcontroller (“MCU”) 20, a Bluetooth module 3, Wi-Fi antenna 14, GSM antenna 8, and a pull tab 2 which prevents drainage of the non-lithium battery 16 until the driver or user pulls it to activate the device 11. The driver needs to be sure that the device 11 selected to be included in the time-critical package is fully charged. The plastic pull tab 2 is used as a switch to connect the batteries with the tracker circuit. The pull tab cannot 2 be re-installed so the driver can confirm it is the first time the device 11 has been activated and fully powered when the tab 2 is pulled.

Non-lithium AAAA alkaline primary batteries 16 are used instead of rechargeable lithium-ion batteries. Using a non-lithium battery makes the device safer for flight safety compliance and transport usage, and has a lower self-discharge current that allow for long storage periods, without losing power. Once the device is ON, a LED indicator will allow the driver or user to determine if the device is ready to be used. A green light indicates that battery level is correct, and connectivity over the GSM network could be established. The driver phone 1 connects with the device 11 via the Bluetooth modem and the device reports 17 reports its unique electronic identification number received or associated from SIM card 18 over the Bluetooth Module 3 signal so every future location reading can be correctly associated to the device package tracking information. The driver or user's mobile communication device such as a cell phone App reports to AirTrace Server 4 the Tracker Id to be used.

From that moment forward, all communication from the device 11 to AirTrace Services, i.e., the server, 4 is done exclusively over the GSM network 12, through the use of USSD messages. GSM network wireless transmission technology is distributed in most countries around the world by wireless telecommunication carriers, allowing for package tracking in almost every country. USSD messages are sent to AirTrace Services 4 through a USSD Gateway managed over SS7 signaling in conjunction with the telecommunication company that provides data access to the uniquely numbered SIM Card installed in each AirTrace device.

Transmission over the GSM network demands more energy than any other single operation performed by the device. Determining the right moment to transmit is thus very important for power efficiency. The device 11 includes an accelerometer 5 that allows device 11 to determine movement, even minor vibration. The accelerometer 5 is then used for two objectives, to prevent the device 11 from transmitting when it is moving by turning off the GSM module 6, thereby preventing any kind of transmission to be done before a plane takes off and until it has landed and the package is not moving any more. The accelerometer 5 is sensitive enough to detect vibrations caused by the plane engines, so no transmission is also intended during flight and when no plane engine vibrations are detected GSM module 6 is turned back on and the device 11 reports its location.

Depending on the shipping en route plan, the AirTrace server 4 may also configure other operation modes during the shipment. For example, if the shipping only requires truck transportation, a message can be sent to configure the device to report its location on a time sequence, regardless of accelerometer readings. The same example applies for a package that did require flight transportation but flight has already occurred and the rest of the shipping is carried out by truck. Another example would be a package delayed in customs for two days, then AirTrace server may instruct the device to stop all activity for a period of time, saving energy for later.

Once the MCU 20 determines a location needs to be reported, it requests a Wi-Fi receiver to scan for Wi-Fi access points that may be near to the device. The Wi-Fi receiver eventually informs a list of Wi-Fi access points, including each Wi-Fi access point Mac Address or SSID, and signal strength RSSI. The MCU 20 will then order the list of Wi-Fi access points by signal strength, and then for supplemental or better location verification ask the GSM Module 6 to scan for one or more GSM Cell tower 13 ID data points detected to be in range of the device. The list of Wi-Fi access points 47 and supplemental GSM Cell tower 13 data serve as location verification reference points that are known by the AirTrace Service 4 through the Wi-Fi access point 47 and cell tower 13 ID location database 9. The MCU 20 will then create a set of USSD messages, each transmitting the collected data in real time and containing a Wi-Fi access point 47 collection data or supplemental cell tower ID information, to be transmitted to server(s) 4 (referred to herein as “AirTrace Service”) over the GSM network.

AirTrace servers receive reference points information, and based on the geographical records kept in one or more Wi-Fi access point 47 and Cell Tower ID location databases, will compare to known Wi-Fi access point 47 locations or attempt to triangulate the device location from multiple location data sources, and record it in the server as part of the corresponding shipping confirmations or exception tracking.

FIG. 3 is a flow chart of an exemplary method wherein an order is created 22, an optimal flight is identified 23 using an airline flight database 10. The device 11 is associated 24 and reported to a shipment tracking application 30. The driver mobile phone 1 application reports acceptance by the package airline shipper or air carrier 25. The device 11 reports and the device signal is verified 26. When aircraft engine vibration is detected, a takeoff signal is received 27 and a flight tracking API service 31 is used to calculate or report an expected package location at various times, for example at a connecting airport, destination airport, and/or truck depot. The system listens 28 for an AirTrace signal and if received 29 the server calculates whether the device is located 30 at the departure airport. If so, operations is notified 31 either of a failure to board 32 or a route deviation 31. If landing is detected 32, the system determines 29 whether device 11 signal has been received. If so, the system calculates whether the device is located at expected arrival airport 30. If located at expected arrival airport, operations is notified 33 of device 11 arrival by server message, otherwise operations is notified 31 of a likely route deviation or shipment location exception.

The device platform in FIG. 3 includes support for a Bluetooth network stack based on the Bluetooth chip inside the location device, which allows the package-positioning device to wirelessly exchange data with other Bluetooth devices (e.g., a delivery driver's mobile phone other mobile computing device).

Bluetooth is managed by the Bluetooth Special Interest Group (SIG), and operates at frequencies between 2402 and 2480 MHz, or 2400 and 2483.5 MHz including guard bands 2 MHz wide at the bottom end and 3.5 MHz wide at the top. The system's application framework provides access to the Bluetooth functionality through the Bluetooth APIs to pair between two devices. These APIs let applications wirelessly connect to other Bluetooth devices, enabling point-to-point and multipoint wireless features. Examples include the device on or inside a package to communicate to a mobile phone or other Bluetooth receiver in range of the positioning device and share it's ID and pair location of a driver's smart phone while en route to airport or other POI area. The benefit of Bluetooth includes not needing to activate the device's Wi-Fi connection to prolong device battery life. Bluetooth function can either be used to complement or in place of Wi-Fi access points for transmitting a unique ID to identify a package in-transit and not yet at an airport or POI. Similar to Wi-Fi positioning, the Bluetooth chip inside device can estimate distance based on received signal strength from Bluetooth Low Energy signals emitted by the Bluetooth sensor and chipset inside package-positioning device that constantly broadcast their presence in range of a second Bluetooth receiver device (e.g., mobile phone or mobile computing device of shipment driver).

In other embodiments, Bluetooth chip inside the package communication device can also be used to associate a user or shipment with an attached tracking device, receiving an indication that the tracking device is lost or misplaced, setting a flag indicating that the tracking device is missing, receiving a location within a proximity of the tracking device from one of a plurality of mobile devices associated with a community of users, and providing the location to the user to help track the location reported based on the crowd sourced location positioning reported by Bluetooth chip and associated firmware within the Bluetooth chip.

The system and method of the invention allows for Bluetooth module and connection protocols, to associate wireless device, and its unique device ID to communicate to third party computer server, and to confirm pickup over mobile app or API that en route delivery by driver has started, and/or to receive instruction to connect the device pre-applied or to be placed by driver by accessing a mobile app running on their mobile device (phone or mobile communication tablet device) for a new package to be first accepted for delivery, requiring driver or other receiving package delivery service to add and attach or receive the package with the novel tracking device already pre-placed by shipper onto a package or part, or placed inside the package. As the driver needs to ship accept and begin package delivery steps on a schedule right away, the driver selects in mobile app the tracker device option to be associated that is fully charged, and activates the power-on pull tab to verify connection over GSM and begin the package's en route journey based on a planned delivery schedule.

From that moment forward, all communication from the device 11 to server 4 is done exclusively over the GSM network 12, primarily through the use of USSD messages. The GSM network 12 is distributed all over the world, allowing for package tracking in almost every country. USSD messages are sent to server 4 through a USSD Gateway 11 managed by the telecommunication company that provides the SIM Card 18 installed on each device 11. Since USSD messages have a limited length of 182 alphanumeric characters, a protocol of communication between the device 11 and the server 4 is in place to reduce the number of messages exchanged as much as possible, since communication of messages is a high power operation for the tracking device impacting device power en route.

Transmission over the GSM network 12 demands more energy than any other operation performed by the device. Determining the right moment to transmit is then very important for power efficiency. The tracking device 11 includes an accelerometer module 5 with firmware built-on that allows MCU 20 to detect and process data from the activity, even minor vibration. The accelerometer 5 is then used to perform one or more of these steps:

-   -   1 Engine vibration patterns characteristic and determined by the         device accelerometer sensor inside device and associated         processing firmware and software to report aircraft engine         flight engine patterns; and/or;     -   2 Prevent the device to transmit when it's moving. After         movement has been detected over a period of time, the whole GSM         Module 6 is turned off. This prevents for any kind of         transmission to be done before an aircraft takes off, and until         it has landed and the package is not moving any more. The         accelerometer 5 is sensitive enough to detect vibrations caused         by the plane engines, so no transmission is also intended during         flight; and or     -   3 Force the device 11 to report its location after movement         ceases.

FIG. 4 is a flow chart of the server operation. The process starts 34 when an order is received 35. The server searches 36 database flight schedules, calculates 37 pickup location, time of pickup, route plan, delivery time, and delivery location. The server receives 38 pickup confirmation from a driver's mobile phone or device, receives 39 Wi-Fi data from the device via GSM, calculates 40 actual location of the device 11 based on Wi-Fi data and a stored Wi-Fi access point location table, compares 41 the actual location at time, Tx, to route plan time-locations. In shipments involving drivers with mobile phones or computing device 1, the system may also consider the driver's GPS location of that mobile phone 1 or communication device and calculate whether a driver has erroneously indicated that a package has been picked. The system calculates 42 whether the device 11 location matches the route plan time location. If not, a notice of route deviation is sent 43; if so, the server calculates 44 whether the device 11 has been delivered to a planned or expected location. The process ends 45 when the device is located to the planned location.

FIG. 5 is a flow chart of an aspect of an embodiment of a method regarding the function of the accelerometer wherein after the device is activated it reports its initial location 51 and obtains an accelerometer reading 52 to determine if the device is moving. If it is moving and the movement persists over a number of readings 53, the RF is turned off and a report is sent 54, the GSM module is toggled to OFF, an accelerometer reading is taken after waiting a pre-determined number of minutes 55, and if the device is moving according to the accelerometer reading 56, another accelerometer reading is taken after a predetermined number of minutes until the device remains still 57 over a preset number of accelerometer readings and the location is reported 58. If the device does not remain still for the preset number of accelerometer readings, the still counter is increased 59 and another accelerometer reading may be taken after a few seconds or other interval.

FIG. 6 is a flow chart of an embodiment of an aspect of the method regarding toggling the GSM module, Wi-Fi module, and use of supplemental cell tower IDs wherein the server requests a location report from the device 61 which turns on the Wi-Fi module and requests a Wi-Fi access point list 62. The Wi-Fi module is turned off after sending the Wi-Fi access point information to the MCU and the GSM module is toggled to ON and a request for cell tower identification information is done 63. After any cell tower IDs are received, the device module defines messages for transmission including Wi-Fi and cell tower information and transmits that information over USSD channel 64 before toggling the GSM module off.

The flow chart of FIG. 6 can access internet databases, such as the FAA flight logs or third party carrier transportation databases accessible, such as FlightAware™ or OAG Flightview™ flight plans database, to further augment the Wi-Fi traces and reporting time(s) with other real-time flight takeoff and landing reporting sources such as geographical information and time constraints (i.e., late flight departure or other FAA database confirmation data that an aircraft has taken off).

Using Wi-Fi signals is faster, more precise and battery-friendly than GPS and cell-towers alone. These databases can also be manually updated to add specific new or private Wi-Fi addresses and can include an aircraft's specific Wi-Fi router or hotspot data to reveal its location, using that Wi-Fi positioning to verify a Point of Interest area such as a specific airport, airport terminal floor or zone, specific aircraft's Wi-Fi or hotspot connection, warehouse or holding area floor, room or even Wi-Fi points adjacent to flight runway area or aircraft shipment loading area(s).

When using the system indoors, an optional database library allows for both manual entry and machine learning by matching to historical Wi-Fi location access points (BSSID/MAC address) linked to a latitude or longitude, room, floor or other very specific location (i.e., United aircraft 33 at JFK Airport, terminal 3) and stored in the system's database. The library provides accurate airport, aircraft, and warehouse-level positioning indoors by accessing its database of Wi-Fi fingerprints and reported data points collected over time or manually entered. The additional fingerprints can be collected from both public and private Wi-Fi hotspot databases that are reported and stored in a database with time stamps for each Wi-Fi hotspot noted and by correlating mobile device location data with Wi-Fi hotspot MAC addresses and other recorded data.

The system estimates the mobile device's current geographic location, latitude and longitude, by using as references one more Wi-Fi signals for location reporting of the package from the attached device, within range. This can also be complemented or augmented by using Cell-ID location data that the attached mobile device receives, in addition to Wi-Fi. The location is reported by using cellular tower networks (GSM, CDMA, 3G, LTE, 5G, LTE-M1, NB-IoT) and across all operators throughout the world. It should be noted that the Wi-Fi system and method only listens for signals and does not attempt to connect or transmit to any wireless Wi-Fi networks. A combination of these techniques may be used to increase the accuracy of the system.

The web services API enables applications to submit via HTTP, SMS or USSD message formats that can include a Wi-Fi access point identifier and signal strength to obtain its geographic location, latitude and longitude, and indoor location data plus an optional confidence radius. The same data can also be reported for a cell id or cell tower identifier data to augment location confidence and reporting.

The GSM location message transmissions by the package-positioning device can also be enabled to add high-grade proven cryptography targeted at small form factor devices and building around that additional security application services such as device identity management. Such cryptography can be added into smart baggage tags and connecting package devices to airline and airport enterprise applications via a secure M2M/IoT cloud application addressing IATA 753 airline industry standard but it also addresses, for example, airport concerns about the security of smart baggage tags and other trackers and the potential creation of millions of insecure mobile hackable endpoints.

Incorporating blockchain in combination with the IoT enabled sensor device attached onto or placed inside packages can add real-time ownership and location journey of package shipments to be shared and managed in a distributed ledger enabling AirTrace Service to be part of a distributed standard.

The blockchain technology can be incorporated to add and share data from the device attached to any object entrusted to someone else for transport, with trackable ownership, possession, locations and telemetry parameters such as, accelerometer data around motion, shock and temperature. The final buyer or package delivery recipient can access a complete record of information and trust that the information is accurate and complete since the blockchain adds an immutable and distributed ledger that can't be hacked. Blockchain permits additional streams of real-time data to enhance analytics and patterns accessible to parties with AirTrace Services that can receive, record and share data from device with GSM sensor data reporting including location and other embedded sensor data such as from the accelerometer with built-in internal thermometer so multiple data telemetry can be shared with trusted accurately and with completeness. Such system can enable chain of custody of a shipment independently to better validate and manage the ownership and journey of a package to be transferred and traded according to smart contracts.

A special feature of the invention is the way it determines whether a device location at various times matches the expected locations at those times. Another special feature is the way the device uses vibration of aircraft engines to turn off the device's GSM module, thereby saving power during the times when the a GSM transmission would be useless and to better comply with aviation regulations.

Overall the device and system includes computer assisted server, device vibration data listening, processing and location determination methods to temporary prevent in-flight radio transmission with transmission deactivation methods designed to be compliant with regulations and restrictions that have been in effect since 2003 when the United States Federal Aviation Administration (FAA) required restrictions on use of mobile communication aboard all aircraft during flight for aviation safety and avoidance of interference with aircraft avionics. This represents an automated computer implemented approach to what airlines require passengers to manually activate their mobile device “airplane mode” before or during flight, as flight safety requirements and regulations require text telephony and other signal-transmitting technologies such as GSM or other wireless radio communications to remain off in-flight.

As defined, a Package is a bundle of something, usually of small or medium size, that is packed and wrapped or boxed. It can represent a stand-alone parcel or a container, as a box or case, in which something is or may be packed for goods, freight, luggage, or logistics transport. It can also be a finished product contained in a unit that is suitable for immediate installation and operation, as an aircraft or other critical replacement part, and can also include items for medical and pharmaceutical transport.

The term USSD (Unstructured Supplementary Service Data) is a Global System for Mobile (GSM) communication technology that is used to send text between a mobile phone and an application program in the network. Applications may include prepaid roaming or location reporting. USSD is similar to Short Messaging Service (SMS). Unlike SMS, USSD transactions occur during the session only. With SMS, message scan be sent to a mobile phone and stored for several days if the phone is not activated or within range. The Wireless Application Protocol (WAP) supports USSD. USSD is defined in the GSM standard documents GSM 02.90 and GSM 03.90.

The term Wi-Fi refers to a wireless networking technology that allows computers and other devices to communicate over a wireless signal. It describes network components that are based on one of the 802.11 standards developed by the IEEE and adopted by the Wi-Fi Alliance. Examples of Wi-Fi standards, in chronological order, include: 80211.a, 80211b, 80211g, 80211n, and 80211ac.

Wi-Fi is the standard way computers connect to wireless networks. Most wireless communication devices have Wi-Fi chips to allow Device to find and discover wireless routers. Most mobile devices support Wi-Fi, enabling them to connect to wireless networks as well. When a device establishes a Wi-Fi connection with a router, it can communicate with the router and other devices on the network. A Wi-Fi “hotspot” includes the geographic boundary covered by a Wi-Fi (802.11) wireless access point. Typically set up for Internet access, a device entering the hotspot with a Wi-Fi-based receiver inside can view the access point in range and configured to advertise their presence (beaconing) and authorization is not necessary.

The term GSM, also known as: “Global System for Mobile Communications, is a generally a TDMA based wireless network technology. GSM phones make use of a SIM card to identify the user's account. The use of the SIM card allows GSM network users to move their phone identity from one GSM device to another by simply moving the SIM card. Currently GSM networks operate on the 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz frequency bands.

The term SIM stands for subscriber identity module or subscriber identification module (SIM) is an integrated circuit that is intended to securely store the international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephony devices (such as mobile phones and GSM devices). The SIM circuit is part of the function of a Universal Integrated Circuit Card (UICC). “SIM cards” can be separate cards or virtual circuit cards and are transferable physically or electronically (e.g., by Internet database) between different mobile devices. A SIM card contains its unique serial number (ICCID), international mobile subscriber identity (IMSI) number, security authentication and ciphering information.

The term USSD Gateway is a session-based protocol. USSD messages travel over GSM signaling channels and are used to query information and trigger services. USSD establishes a real time session between mobile device and application handling the service.

The term SS7 signaling is the core signaling/control protocol used within fixed and mobile networks. The SS7 network is an interconnected set of network elements that is used to exchange messages in support of telecommunications functions.
